Is there a chemical (been trying to avoid that but at this point I don't care anymore) that I can use that won't harm the tree/bushes but will kill weed growth?
Or do I just keep pulling hoping for the day when there will be no more weeds?
Any other suggestions?
Thank you.

What we first thought were weeds in the shrubbery bed, and tried to pull them out, we found that they were long rhizomes from the St. Augustine grass that propagates that way. Found out the lawn guy was not edging around the planting beds to prevent their spread. Found another lawn service who did the proper job plus sprayed a Roundup like product (non cancerous) to kill the remaining little weed sprouts that pop up.
